Abstract: PURPOSE:To enable accurate temperature control by providing the coating layer of a temperature indicating member which changes in color reversibly according to whether the temperature varies, detecting the color change optically and detecting the temperature, and controlling the temperature of the surface of a roll. CONSTITUTION:A mandrel roll 8 is coated with thermo-paint which changes in color reversibly according to temperature variation to form a thermo-paint layer 9 to 0.5-50mum thickness. This member changes in color by the dislocation of the crystal type of a pigment compound in use with heat. Then this color change is detected by using a noncontact type optical element 11 to perform the temperature control. The delay of response in this case is only the response delay of the applied reversibly heat-discoloring member and the delay of the optical element 11 and the part for controlling it can nearly be ignored. Consequently, the follow-up performance of temperature variation is good and the accurate temperature control is enabled.
